XZ Micro Translation Stage 7T228T provides smooth, precise two axis movement. The driving screws are positioned so that the unit is controlled only from one side. That's why 7T228T is very handy in optical schemes with very dense placement of instruments. The travel of this stage is 4mm with sensitivity of 5m. To mount components on it, M2 tapped holes are provided. The unit has a clear aperture of 7mm in diameter. So it is ideally suited for use as a holder of diaphragms. The stage can be directly mounted on breadboards and other Altechna equipment by use of mounting holes M3 and M2. Angle bracket 2AB128 may be used to combine the stage with other units. The base and the platform are made of black anodized aluminium.
